Ch. 5 Ecology Each new day is designated by a green background

Once you are done with your test Glue in ch. 5 objective and complete your pre-assessment Create a vocabulary list for the following words Population density Geographic range Growth rate Age structure Immigration Emigration Self evaluation of objectives Take Test on ch. 4

Factors That Affect Population Growth Birth Rate Death Rate Immigration (into a population) Emigration (out of a population)

Why is it important to study populations? ET: In your notebook, answer the following question: Why is it important to study populations? Learning Targets: today I will… Identify methods for how ecologist study population Develop methods for study populations

You are an ecologist studying populations of Canadian geese in Fort Steilacoom park. You have to collect one of the following pieces of information: (Mrs. Sortore will assign your group one) Size of the population Geographic range within the park How fast the population is growing (Birth/death) With your group, develop a plan for how you are going to collect this information (15 min.)

Create a Field Study to collect your data 20 min. Read through the rubric Can you find all the rubric items in your field study? Modify your plan so that your field study includes all rubric items – create a poster with your methods Controlled methods for collecting the data (consistency) Data table / diagrams Number of times this will be done Duration of the study (how long)

Group Share/Critique Using your field study rubric you are going to assess another groups field study Use the sticky notes at each group to ask questions and provide constructive feedback Please leave at least one comment/questions per. Field study you visit

UNTAMED SCIENCE!!! In your notebook, write down the methods you see ecologist using to collect data *Reminder – we are going outside so dress for the weather in closed toe shoes and a coat

5.1/5.2 Limits to Growth ET: What is carrying capacity? What factors determine carrying capacity? LT: Today I will Practice calculating population density Identify different types of distribution for a population Explain how the density and distribution effect a population (density dependent factors)

Describing Populations Density and Distribution Population Density = number of individuals per unit area Distribution = how individuals are spaced Random Uniform Clumped p. 130-131

Lets Practice! In these 2 models you will practice calculating populations density and identifying density dependent limiting factors

Q: A mutant for of lice has appeared in a population, explain possible outcomes for the below two scenarios Population 1: low density and random Population 2: high density with clumped distribution

Limiting Factors Density Dependent Competition Density Independent Predation or Herbivory Parasitism Stress from overcrowding Density Independent Unusual weather Natural disasters

Field Study ET: LT: Today I will… Review your vocabulary words for this chapter (2 min) Have the person across from you quiz you on your words Population density Age structure Immigration Emigration Carrying capacity Geographic range Distribution (3 kinds) LT: Today I will… Conduct a field study to investigate common weed populations on a school lawn

Logistical vs. Exponential Learning objectives: today I will… Differentiate between logistical and exponential growth in a population Compare human growth to logistical and exponential growth ET: What is demography?

Draw the model on your paper

Answer the questions below

Logistical Growth 3 phases Exponential Growth Growth Slows down Growth Stops

Exponential Growth When conditions are ideal and resources are unlimited populations will just get larger and larger and larger and larger and larger…..

Analyzing Data Pg. 135 Multiplying Rabbits

The Human Population Q: Is human population growth exponential or logistical? Why? (private think time, answer in your notebook)

HUMANS Age Structure LT: Today I will… ET: From last class Describe The 3 phases of demographic transition Create age structure diagrams Claim, Evidence, Reasoning (CER) with age structure diagrams (interpreting data) Age Structure ET: From last class What can we infer about the population below? HUMANS

Q: What is this graphic showing Q: What is this graphic showing? Talk with your group and each will share out What is this diagram depicting?

Age Structure Diagram Features Title Age in years Gender # or % of the population

CER – Claim, Evidence, Reasoning With your group, you will develop a claim/inference about that population What evidence from your age structure diagram led you to this inference Provide reasoning behind the data used

6.1 A Changing Landscape LT: Today I will… Describe the relationship between resource use and sustainable development. Explain the pros and cons of different modes of renewable and nonrenewable resources ET: How do our daily activities affect the environment? (list 3) Key vocab: renewable resource, nonrenewable resource, sustainable development

Resources Non-renewable Renewable Oil Wind Coal Water Natural Gas Uranium Renewable Wind Water Solar

Sustainable Development Using natural resources without causing long term damage to the environment (soil, water, climate)

Examples of Sustainable Development

Answer The Following Questions Pg. 158 What is soil erosion? What causes it? what is desertification? What is biomagnification? What is DDT? Why are both bad? What are the major forms of air pollution? What causes acid rain?

Soil as a renewable resource Soil Erosion Why is it bad? What are the main causes?

Fresh Water What is Biomagnification? Why is it important?

Atmospheric resources What are the major forms of air pollution? Smog, acid rain, greenhouse gasses, and particulates

Biodiversity 6.3 LT: Today I will… Define biodiversity and explain its value alter habitat and the affect that it has on the biosphere ET: What does the word “diversity” mean? Define Habitat Fragmentation Ecological hot spot

Threats to Biodiversity: Discussion Altered Habitats Hunting and the Demand for wildlife products Introduced Species Pollution Climate Change

Conservation of Biodiversity (Untamed Science: Zoos) Protecting individual species Preserving habitats and ecosystems (hot spots) Considering local interest
